Tank Tests of Model 11-G Flying-boat Hull
This is a 1935 NACA technical report, published by the National Advisory Committee for Aeronautics for aeronautical engineers and researchers, presenting tank tests of a flying-boat hull model. Its pages are dense engineering line graphs of resistance, trimming moment, and trim angle plotted against speed in feet per second, with curves labelled by load in pounds. A designer might take from them the clean grid-and-curve vocabulary of technical charts: plotted data lines, labelled series, and restrained monochrome plates.
